Service Analysis of Tube Vehicle Systems

This report describes an analysis of the service characteristics, cost and performance of Tube Vehicle Systems operating within the Northeast Corridor of the United States in the 1975 to 1985 time frame. The basis of this study is the TRANSOP computer program which, as described herein, searches...

Rock Fracture Research- Surfactants

In order to reduce the resistance of hard rocks to excavation by available cutters, and in order to reduce wear on cutters and thus to increase the efficiency of conventional tunneling machines and thus improve their rate of advance in hard rocks, surface active agents have been studied in...

Resistance of a Freight Train to Forward Motion- Volume II, Implementation and Assessment

This interim report is a supplement to a previous report and documents the results of the second portion of an investigation of the train resistance phenomenon. This portion of the effort was specifically directed toward determination of possible fuel savings to be effected through certain design...
